Degree shims for rear springs

[roke40]

I'm swapping out my 3" skyjacker pack for a 4.5" RE spring pack and I have the ORGS lift shackle (about 1 inch lift). My skyjacker packs came with the shim built into the spring pack so I didn't need to worry about that. But from what I can see the RE springs don't. What are you guys with similar setups running so far as degree shims?

Every rig is a little bit diffrent. The best way to do it is to buy a few diffrent angles and measure the pinion when you set the springs down.

I'm running 4.5" RE springs with a 1.5" lift shackle and 4 deg shims.
